Oryginal question at the end. Thanks for the answers from: Stephen Boronski hmnguyen@verizongni.com Kevin Buterbaugh In general: - you will get the best performance if your UFS block size matches the Oracle block size. - Based on your disk layout, data chunk are going to read/write across all three disks. Because of several disks arm are doing I/O, this already given your system better in performance. I will stick with default options of newfs. przemol ================================================================= Subject: E 450, oracle, cluster size etc We have E 450 with 2 internal expansion kits. We are going to install Oracle 8i on it. My configuration of disks is as follow (I removed configuration of root and swap): d8: Mirror Submirror 0: d6 State: Okay Submirror 1: d7 State: Okay Pass: 1 Read option: roundrobin (default) Write option: parallel (default) Size: 105492256 blocks d6: Submirror of d8 State: Okay Hot spare pool: hsp001 Size: 105492256 blocks Stripe 0: (interlace: 32 blocks) Device Start Block Dbase State Hot Spare c3t0d0s0 0 No Okay c3t2d0s0 4712 No Okay c3t3d0s0 4712 No Okay d7: Submirror of d8 State: Okay Hot spare pool: hsp001 Size: 105492256 blocks Stripe 0: (interlace: 32 blocks) Device Start Block Dbase State Hot Spare c5t0d0s0 0 No Okay c5t2d0s0 4712 No Okay c5t3d0s0 4712 No Okay Our oracle admin has decided that oracle block size is going to be 16 kB. Most of database files will be put on d8 filesystem. What are the most optimized parameters (for newfs or mkfs) which should be used during creating filesystem on d8 ?Received on Wed May 23 10:07:44 2001
